How to fix Gmail blocking email from Hover

I use Hover for my domain registration and email. I couldn’t send emails to Gmail addresses, as they were all bouncing back.

<john.doe@gmail.com>: host gmail-smtp-in.l.google.com[***.***.***.**] said:
550-5.7.26 This mail has been blocked because the sender is
unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with
either SPF or DKIM. 550-5.7.26 550-5.7.26 Authentication results:
550-5.7.26 DKIM = did not pass 550-5.7.26 SPF [lucaf.eu] with ip:
[***.***.***.**] = did not pass 550-5.7.26 550-5.7.26 To mitigate this
issue, please visit Gmail's authentication guide 550-5.7.26 for
instructions on setting up authentication: 550 5.7.26
https://support.google.com/mail/answer/81126#authentication
k33-**************************.*** - gsmtp (in reply to
end of DATA command)

The error 5.7.26 is caused by Gmail’s Sender Policy Framework (SPF) requirement, which is not created by default for Hover’s email service. To fix the error, follow this guide and create a SPF record for your domain.

The record suggested in Hover’s guide fixed the issue for me.
